AmpOp Universal PCB

[Elektor78]

Hi to all 😀

I am trying to draw a small AmpOp PCB for general use and experiments
with small Pdip 8 pin single amplifier Ac or Dc coupled..
As a modular system where I can add or remove modules or components
in order to obtain various configurations


it could work?
Suggestions always are appreciated 😀

bye 🙂

ouch ! I have forgot the draw...

An externally hosted image should be here but it was not working when we last tested it.

I would want also to try to draw a pcb for a universal active filter (Low or High Pass)
Wich type for a chain of AmpOp ?
Active Filter
Sallen Key Type
Multi feedback

Thanks 🙂

If I build a dc chain of amp-op I imagine that the dc offset is very important
because a little dc can be amplified to the next stage.. 🙄

If I need a 60dB two stage amp-op wich is the best split" gain for each amplifier ?
20dB + 40dB or 30dB + 30dB or what (with dc couplind) ?

Thanks.. 😀
